摘要:

为了研究烯效唑对鲜食甘薯生长特性和产量的影响,以心香品种为试验材料,进行了4个不同浓度处理的对比试验。结果表明,喷施烯效唑所有处理的地上部与地下部鲜重比均低于对照,鲜薯产量和叶绿素相对含量均高于对照。说明喷施烯效唑能相对地延缓地上部生长,降低地上部能耗,提高光合效率,从而达到增产的目的。本试验中,以喷施75 mg·L-1烯效唑处理效果最为理想,其667 m2鲜薯产量为2 528.46 kg,比对照增产13.35%,建议在生产中推广使用。

Abstract:

In order to study the effect of uniconazole on the growth characteristics and yield of fresh sweet potato, four comparative experiments with different concentrations were carried out using Xinxiang as the test material. The results showed that the ratio of fresh weight between the aboveground and underground parts of all treatments treated with uniconazole was lower than that of the control, and the yield and chlorophyll content of fresh potatoes were higher than those of the control. The results indicated that the spraying of uniconazole could relatively delay the growth of the aboveground, reduce the energy consumption of the aboveground, and improve the photosynthetic efficiency, so as to achieve the purpose of increasing yield. In this experiment, spraying 75 mg· L-1 uniconazole is the best, its yield of 667 m2 fresh sweet potatoes was 2 528.46 kg, which was 13.35% higher than that of the control.

Key words: uniconazole, sweet potato, yield, growth characteristics
